Lua Class System - Object Oriented Library For Your Projects

I am sharing a small work of my own, a clean and light-weight class system I have been working on. Lua Class System (LCS) is a library for (pseudo) object oriented mechanisms. It aims to be something clean, simple to use, minimalistic so that it would easily fit in every project where object-oriented concepts might be needed. Hope some might find it useful. I am still maintaining it so small changes could occur in... More...

Invert, Horizontal Flip and Vertical Flip Physics Shapes

I recently discovered that is was very easy way to invert images, e.g: myObject.xScale = -1, will horizontally flip a display object. This works well but it will not flip any custom physics shapes assigned to the object so in order for the objects to have the correct physics the shapes need to be flipped also. Here is a function I created which will output a new list of flipped or inverted shapes coordinates from... More...

Simple Polygon Triangulation

I've been looking for a way to break a simple polygon into component polygons for a while. I won't tell you why because I'm using it in a game, but I just had to share this solution. It takes any clockwise winding polygon (entered by tapping the screen in sequence) and breaks it into it's interior triangles - literally "triangulation." I can't take credit for the math, which was the only complete and understandable... More...

OWL (Objects with Lua)

OWL is a single-module library that provides an easy way to incorporate object-oriented programming concepts into Corona SDK projects. Supports classes that produce display objects (as well as classes that produce non-display objects), and can even be used with non-Corona Lua scripts as well. Features include: More...

Cat-mull-rom open and closed

So, got back into the old bezier stuff again and figured it might be fun to try and get the curve passing straight through the control points. Makes it more useful for plotting courses for game characters, because players are not going to be drawing lines and placing control points - they'll just drag out a path or whatever and the character should traverse it, etc...

Texturemapped Raycasting Engine

As a follow up to my original code share of the Corona port I did of my 2D raycasting engine, texture mapped walls have been added. This was achieved using sprite sheets. The downside of this is the frame rate takes quite a hit compared with the flat filled walls shown in the original sample. I know I can optimise how I use sprites in this demo, but I still think more needs to be done to get the frame rate up -... More...

I saw a several questions about this in the forum, and never really found a solid answer, so I thought I would share the code I worked up.

Pauseable Transitions, unified timer and transition module, can replace built-in

Here is yet-another pausable transition library. I call it "ctrans", short for "custom transitions". It is different in that it keeps track of all transitions internally, rather than just tag on data to tween objects. This keeps the size of the tween objects small and allows you to perform actions on a large set of transitions with a simple command. More...

It's really messy, not object oriented but it shouldn't throw too many errors and I've tried to handle the object removal etc reasonably well.

Ultra Simple Parallax Scrolling

So this is a parallax scrolling module that will handle up to 5 "layers" of parallax. This is made for landscape orientation, but you should be able to just flip a few things in the file and make it work for vertical as well. You can insert as many images as you want within each layer (minimum of 3, I don't think it'll work properly with only 2). Also, all images within each layer will need to be the exact same size...

The directions shown are - UP - UP LEFT - UP RIGHT - LEFT - RIGHT - DOWN - DOWN LEFT - DOWN RIGHT This is useful in cases where you need to change the image based on the direction of object or if you need to code a joystick. 1 2 3 4 5 6 7 8 9 10 --to store previous position of x and y local prevx = 0 local prevy = 0 local circle = display....

Keeping score aligned

Hey, i don't know if someone has posted something similar to this, but I couldn't find one, so I wrote my own.

PuzzleApp

This sample code is a demonstration of how you could implement a simple jigsaw puzzle concept using the Corona SDK's bitmap masking functionality. I created this a long time ago and it was just sitting on my harddrive, so I thought I'd put it to good use and share it with the developer community. It is optimized for Galaxy Tab/Nook dimensions, but could of course be tweaked to match any dimensions. It's the logic... More...

Arrow Basics

I needed an arrow for my game but quickly found out that it doesn't move properly (arrow head wouldn't point down with gravity) so I came up with this. This is the basics of how an arrow should work in Corona. I figured out how to do this with the help of peach pellen and the forum user canupa.com. Also the magnet code was taken from the gravity sample code written by horacebury. Coded by Nick Homme More...

Pauseable timers and transitions with speed adjustment

After searching for pausable timers for corona I found only several implementations. Beebe used enterFrame listener to implement his own timers and transitions. Transition manager has memory leaks and lacks some functionality. So I decided to wrap around existing corona timers and transitions into my own implementation. Remember to free the memory used by this module, I advice you you to call... More...

LuaFSM

A design pattern for doing finite state machines (FSMs) in Lua Finite state machines can be used to force (at least parts of) your code into deterministic behaviour. I wrote this code to implement generic graphical objects where the presentation and behaviour of the objects can be specified by using state-transition tables. This resulted in less code (and less bugs), a higher modularity and above all a reduction of... More...
